I might have mentioned that I'm writing encyclopedia articles just now as well as editing a section in the encyclopedia. There are just a few articles I'm responsible for that still need a bit of revising, but theoretically I have 6 more to write myself by Monday. Before I left last night I went over one of them changing some things, including stuff I was sure I'd already changed. Sure enough, I just found a version of the paper that already had some of the changes in it. Which means that where I am now is more or less where I had already got to a couple of weeks ago. Grrr! The reassuring thing is that a lot of the changes I made yesterday are more or less the same as the ones I'd made before.
